Low disk space on “Filesystem root” 500 megabytes disk remaining

[suryapts007]

Hello everyone,

I am struggling against disk space, regarding root location.

Seems like I have reached almost 100% usage, and cannot find a way to regain space.

Though, I have installed ubuntu 20.04 just 14 days ago and assigned 20gb of root space.

When I do df -h, it gives following output:
